Tests for SqlCe using Northwind.sdf

First let me thank you for your efforts in this project! I'm late to the party with implementing LINQ and have so much to learn still. Anyways, I have been working on getting your Northwind tests running with the various database providers. I've succeeded
with the Access version and Sql Server. However, running the tests for the SqlCe version using the Northwind.sdf that came installed with MS Sql Compact Edition fails. The database uses spaces in the column names, so it couldn't find those columns. I then
adjusted the Column Name attribute mappings to be the same as the database column names with spaces. The 'NorthwindTranslationTests' all ran perfectly. The 'NorthwindExecutionTests' tests ran, however there were several errors. I'm just going to
show you only a couple errors because it may be a simple mistake on my part that you might recognize.
